Black Friday & Cyber Monday 2012 – Which Website had the Best Performance?
We monitored the web performance of 70 websites (Excluding Netflix, Blockbuster, 1800 Flowers, Scholastic, and Redcats USA ) from our US Nodes using Internet Explorer 8. The goal was to compare the performance of the sites and to see how well each website handled the traffic during the event.
This year we did not see the same issues as last year, most companies were very well prepared to handle the traffic surge. The only interesting development this year was the number of issues related to 3rd parties tags on web sites.
